How can I tell if the hose faucet outside of my house is slip or threaded on? My house, in Albuquerque, is about 3 years old. I would like to remove the hose faucet and install an elbow. I am afraid to try and turn it in case it is a slip connection and then I break it. The house is stucco and it would be a pain to try and install another slip connection since the stucco is right up to the faucet. Oh ya I also noticed that there is an A on the side of the faucet. I went to a local home improvement store and noticed that the threaded ones have an A on the side and the slip do not (all brands). Does this really mean anything?
